Haneda is a busy hub for Japan Air Lines (JAL).  While you visit, there will be a steady stream of JAL 737s coming and going so, another one arriving is no cause for interest.  However, I realized that this particular jet did not actually say Japan Air Lines on the fuselage.  Instead, it was marked Japan Transoceanic Air.  I had never heard of this airline before.  A little research shows that it is part owned by JAL – hence the use of the common livery – but there are other shareholders. Occasionally they will lend aircraft to JAL but they do operate to Haneda so I don’t know whether this was a JAL flight or one of their own.  A new airline for me, though.
